Thanks for the feedback.
VMWI has been on our list, but just hasn't been implemented yet.
Basically we just need to write something to notify the ATA.
Here's some background. I always like to justify some of my thinking.
Let's take ViaTalk...I mention this just to give a comparison of how it's implemented since I have some knowledge of their infrastructure. They actually use Asterisk servers and everyone "registers" to an Asterisk server. They also use Asterisk for voicemail.
We only use Asterisk for voicemail and no one registers to Asterisk. Since Asterisk has VMWI built in, it's pretty easy to use it because everyone is registered to it. Since we only use it for voicemail, we have two choices... We can either have all our ATAs communicate with Asterisk or we can write something to basically signal the ATA when there is a message in the database.
Since it involves writing something, there were some variables in terms of different ATAs, etc. We also looked at completely doing away with Asterisk for voicemail even because it just does not scale well at all (as some of you may have experienced).
Now that we have those two variables (ATA type and sticking with Asterisk for VM), we can get this in place pretty easily.
I'd look for it very soon.
